Does it matter how many miles on a vehicle if so what is too miles

timing belts if lucky can go 80,000 miles...a few nutters have pushed it to
120,000, but will get loose and teeth can get stripped off....a TIMING Chain
engine needs a new chain at 150,000 miles....me own Toyota said
goodbye, at the post office, the distributor would not turn....I had AAA tow it
to the house and put a new chain on there in the rain....should have done
the headgasket too.....but it was raining at the time....~

the R50 engine for the MINI has a timing chain that I needn't think about for
the rest of it's life....a R52 engine like the Cooper S has a BELT and needs
to be changed at 30,000 and 60,000 for reliable service~ .....see the
difference here...one is "disposable" and we should hope they took
preventative measures to avoid an interference situation (cupped
pistons....delayed action)~ a non-interference can run until the thing
breaks...just be packin' a replacement in the trunk~
